## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__notavibe__compare_projects` `mcp__notavibe__get_project` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** Long descriptions in `search_projects` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,766 characters long, over the 2,000 this check looks for.

description ends: "...hythm and contribution-breadth health bands. Read-only. Serves catalog schema v1."
```


## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `compare_projects`

- The name "compare_projects" says "compare": a word for reading.
- Tag private-data: The description's first sentence says "return" and "repo": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Return the public profiles of two catalog projects side by side, identified by host and two owner/repo slugs. The response presents each project's facts and health bands; it draws no conclusion and names no winner. The pair is refused when either project is unavailable or has insufficient measured signals. Read-only. Serves catalog schema v1.
```

### `get_lists`

- The name "get_lists" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the public curated lists in the notavibe catalog, or return the public members of one list identified by owner handle and list slug. Only public lists and their publishable members are returned. Read-only. Serves catalog schema v1.
```

### `get_project`

- The name "get_project" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "repo": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Return the public profile of one catalog project, identified by host and either an owner/repo slug or a numeric repository id. Both host and one of slug or id are required; a call missing them is refused as an invalid argument and names what is missing, which is distinct from the not-found given for a well-formed lookup that matched nothing. This resolves any project the catalog holds, including one below the discovery floor that search does not return. The profile carries the claim state, verification or generation provenance, the six vocabulary dimensions, the five health-signal bands, license and package-registry facets, and staleness. Health signals are reported as bands, not raw measures; no person-derived counts are included. Read-only. Serves catalog schema v1.
```

### `search_projects`

- The name "search_projects" says "search": a word for reading.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Search the notavibe catalog of open-source projects. The query matches project name, project description, and the category, ecosystem, kind, runtime and license_family vocabulary facets; free-form repository topics are not matched. A facet match adds a project to the results and does not affect its position in them: results are ordered by how closely the query matches name and description, then by published health signals. Every word of the query must match. A project's description is generated from its facets until its maintainer claims it and writes their own, so a query describing what a project does, such as "http router" or "date parsing", matches only where those words appear in a project name, in a claimed description, or among the words a facet value matches; a project name or a category, kind or ecosystem word is what a generated entry reliably matches. The catalog currently covers one ecosystem: javascript-typescript. category, ecosystem, kind, runtime, license_family and topics are also exact filters. Every filter supplied is applied, and a filter combines with the query rather than replacing it: query with ecosystem returns only projects that match the text AND carry that ecosystem. A filter narrows the result set and never changes the order. category, ecosystem, kind, runtime and license_family accept only values from this catalog's managed vocabulary; a value outside it is refused and the refusal names the accepted values, so it is never returned as an empty result. topics is an open set, so any topic is accepted and an unrecognised one simply matches nothing. The full vocabulary is available from the catalog facet enumeration. The response echoes the filters that were applied. Search returns projects at or above this catalog's discovery floor — a repository whose measured activity is too low to be ranked is held out of search even though the catalog holds it and has signals for it. A call with a query also returns projects in the settling hold, a waiting period a new or changed entry serves before it can be ranked. A call with filters and no query lists ranked projects only, so it excludes projects in the settling hold. An empty result therefore means that nothing matched among the projects that call can return, which is not the same as the catalog having no such project: a project known by name can still be retrieved by exact identity with get_project. At most 100 results are returned; the response field truncated is true when more matched and the list was cut at 100, and no total is reported. Returns compact result rows: repository host and numeric id, slug, name, description, claim state, category, and the maintenance-rhythm and contribution-breadth health bands. Read-only. Serves catalog schema v1.

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `notavibe`:

      "mcp__notavibe__get_lists"
    ],
    "ask": [],
    "deny": []
  }
}
```
